Is this Squawbush (Rhus trilobata)? Upon a quick glance when taking the picture, I thought it was a little oak of some kind.
Hi, Not familiar with the plant first hand, but certainly looks the same as the one pictured on the following site. http://www.blakenursery.com/RhusTrilobata.html Harry
Oaks don't have triangular leaves, divided to the base. Poison oak is similar to this one because it is actually another Rhus.
Certainly looks like it to me. And it does grow in Texas. Try looking it up also under Rhus aromatica, a name also applied to this plant.
